Application filed November 19, 192%. Serial No. 750,765.

lie it known that I, JULiUs L. CABLE, a citizen of the United States,and resident of Boston. in the county of Suffolk and State ofMassachusetts, have invented an Improvement in Folding Camp Chairs, ofwhich the following is a specification.

This invention relates to that class of folding' camp chairs or stoolsin which the bottom is of canvas or similar flexible sheet material and,more particularly, to chairs of this type which are constructed fromsemi-tubular metal.

In the construction of chairs of this type considerable difficulty hasbeen encountered in providing suitable means for attaching the canvas tothe metal cross bars of the chair, attachment by means of rivets beingunsatisfactory and unreliable, and the object of my invention is toprovide a simple and eflective means for connecting the canvas seat of acamp chair of the above type with the cross bars of the chair which willbe as strong as the material of which the seat is constructed, and whichis so arranged that the actual expense of construction will be no morethan that of previously employed methods.

I accomplish these objects in the manner hereinafter described and asillustrated in the accompanying; drawings in which 2 Fig. l is a sideelevation of a folding); camp chair embodying my invention.

Fin. 2 is a similar view showing; the chair folded.

Fin. 3 is a detail sectional view of one of the cross bars and topportion of one of the legs.

Fig. 4: is a longitudinal sectional view at line a2a2 of Fig. 3.

Fig. 5 is a sectional view of one of the cross bars.

Fig. 6 is a side view of a cross bar, partly in section.

Fig. 7 is a detail view of one end portion of a cross bar prior toassembling.

In the drawing a common type of-folding camp chair is illustrated, whichcomprises two pairs of legs 1 and 2 formed of semitubular metal andpivotally connected in the middle thereof, so that they may fold in theusual manner, as shown in Fig. 2.

According to my invention 1 provide a pair of cross bars 3 and 4 forconnecting the opposite legs their upper ends and a and ears on thelegs.

towards each other atright angles, to form retaining flanges or lips 6.The upper end portions of the legs are flattened to form ears 7, whichare adapted to enter sockets 8 at each end of the cross bars, the lengthof said sockets to the lips 6 and the width of said cars corresponding.

In assembling the parts above described, the canvas seat is turned overand sewed to provide with a simple form of hem 9 at each end and givethe canvas treble thickness at these points. The distance between theedges of the flanges 6 is only sufficient to permit a single thicknessof the canvas to extend therethrough and in assembling the canvas andcross bars the hems are drawn into the bars at either end, until thesides of the strip are even with the ends of the bars, in which positionthe canvas will extend between the edges of the flanges, and its hemswill be retained within the bars by their engg'agament with the flangesas shown in Fig. 5. The canvas is then wound part way around each barand the sockets at the ends of the bars are then placed on the ears 7.as shown in Figs. 3, 4, and 6. are then passed through the sides of thebars, the intervening; ears 7 and hemmed portions of the canvas, andthen these parts are clamped closely together by the rivet ing processas shown in Fig. 3. As thus arranged the canvas extends from each barabout its outer side and over its upper edge, completely covering theexposed portions of the bar. The half turn, which is thus taken abouteach bar by the canvas, relieves the strain which would otherwise beplaced on the hem, which is drawn into engagement with the lips 6, to asubstantial extent. This strain is further relieved by having the endportions of the canvas firmly clamped between the sides of the crossbars The canvas as thus arranged, completely covers the sides and top ofthe bar and gives the chair a finished appearance, and the strain on thecanvas Rivets 9 llt),

will be uniformly distributed throughout its entire width. The crossbars, oanvasand legs will also be securely hound together so that theseparts will be rigidly held in the relative positions shown.

The chair may he provided with it back 10 which is pivotally connectedto opposite legs.

I claim:
